Project V - 13. Security System with RFID based On Arduino

Security System with RFID

RFID-RC522 module is a module used for data reader of RFID card. Any RFID or other RFID Tags may be keychains and so have unique IDs, or one with another are different. The ID is used to be programmed as a security, so when there is an ID that does not match the program, then Arduino will give the command that the ID does not match. In this project when the ID of the RFID matches, it can be used to control the Relay which can then be connected to another device as a security. So, before trying this project, then you must know in advance the ID of the RFID card you have. The RFID Card ID Reading Program has been available on this blog under the title "Interfacing RFID".
